"I don't think so," Mayhew said. "Those are all Jim's decisions, and we talked about those as they were being made. I'm supportive of his decisions, but it's his staff. He has to have his staff that he feels comfortable with as best in his mind, in terms of being ready to win games in 2013."

Mayhew did not rule out the potential front office changes, but declined to talk specifics.

"Yeah, certainly (there could be changes)," Mayhew said. "We're evaluating everything. We're evaluating the front office, we just finished evaluating the players in our meetings today, we're obviously evaluating and have evaluated the coaching staff, and we're looking at all options in terms of how we get better, how we make better decisions in the front office, how we improve our decision-making process. All those things are on the table."
